Omni.Anim.People demo scenes not working

[abhilashcashok]

Hello,

I am trying out the default demo scene for Omni.Anim.People - Omni.Anim.People — Isaac Sim 4.2.0 (OLD). I opened the simple_event_simulation.usd.

Few things I noticed:

1. Only characters are added to the stage
2. No warehouse environment is loaded (as shown in the documentation)
3. On PLAY, nothing happens. The characters pose changes from T-Pose to idle pose.

Isaac Sim Version

4.2.0

Operating System

Windows 11

GPU Information

• Model: GeForce RTX 4050 Laptop GPU
• Driver Version: Studio Driver v551.61

Steps to Reproduce

1. Follow the steps mentioned in Run A Demo Simulation - Omni.Anim.People — Isaac Sim 4.2.0 (OLD)

Error Messages

Log file from Console is attached.
issac-anim-people-log.txt (1.5 MB)

Screenshots or Videos

Additional Context

I have tried the same sample in Issac Sim 4.5. But, USD was not loading and the file size is shown as zero.

Any idea what is missing and how to make this work?

Thanks in advance.

I tried setting up simulation from scratch - Omni.Anim.People — Isaac Sim 4.2.0 (OLD).

That too didn’t worked.

The command I use is male_adult_construction_01 GoTo 2 -5 0.

Few things I noticed, the neck and chest part is not set for the character. I couldn’t find a matching value for that.

This is same for Biped_Setup

Any thoughts.

I have asked the Isaac Sim team to respond to this asap. However the first thing you should do is upgrade. For sure. You are using the old version. The new version is 4.5. So please upgrade first.

Hello, it seems that there are some issues with our Isaac Sim 4.2 asset – it should load the warehouse environment but it’s completely empty.
Please try the isaacsim.replicator.agent extension in Isaac Sim 4.5 – Agent Simulation Synthetic Data Generation — Isaac Sim Documentation
The omni.anim.people UI has been deprecated in Isaac Sim 4.5 in favor of isaacsim.replicator.agent. It is more powerful and it does everything that omni.anim.people can do, with a lot more automations.

Thank you @Richard3D for the follow up. Much appreciated.

@Haoquan_Liang Thank you for the reply. I will try with v4.5. The challenge is my project is almost completed in v4.2 except the People simulation. Not sure upgrading to v4.5 breaks any existing implementations as it is due for delivery in coming weeks.

I will try v4.5 and will give an update by Monday.

Thank you for all the help. Highly appreciated.

@Haoquan_Liang I finally made the character walking in Isaac 4.2.

Here is what I had done.

1. I tried Tom Jerry example which loads 2 characters along with biped setup
2. I then adding new character following Setup Simulation From Scratch - Omni.Anim.People — Isaac Sim 4.2.0 (OLD)
3. I provided command male_adult_construction_03 GoTo 0 -5 0 90 which worked

However, I am facing another problem here. The sequence of commands is not respected by the character. If my character is at 0,0,0 with command male_adult_construction_03 GoTo 0 -5 0 2 -5 0 90. The character is directly going to 2 -5 0 from 0 0 0 in a straight path. As per documentation, it should got 0 -5 0 and then to 2 -5 0.

Any thought on this?

Hello @abhilashcashok ,
You need two commands for two target points.
male_adult_construction_03 GoTo 0 -5 0 _
male_adult_construction_03 GoTo 2 -5 0 _

isaacsim.replicator.agent is also available in Isaac Sim 4.2. It was named omni.replicator.agent.
You can find the 4.2 doc here: Agent Simulation Synthetic Data Generation — Isaac Sim 4.2.0 (OLD)

@Haoquan_Liang That worked. I added commands line by line and characters are moving around as expected.

The documentation wrongly suggests using character_name Goto x1 y1 z1 x2 y2 z2 x3 y3 z3 end_rot which is incorrect.

Thank you for the timely help. Much appreciated.
